Macroscopic examination of the fetuses revealed additional skeletal abnormalities such as micromelia, bowing of the limbs, and craniofacial dysmorphism. The craniofacial features included relative macrocrania (larger head size in proportion to the body), hypertelorism (increased distance between the eyes), a small nose with anteverted nostrils (nostrils pointing forward), a long philtrum (the groove between the nose and upper lip), thin lips, microretrognathia (smaller-than-normal lower jaw), and low-set ears.
